public interface GraphGenerator

Contructs a graph based on relationships between the entities (objects) modelled by the graph.

The underlying graph is generated by continually adding objects to the generator. The Generator determines the relationships between the objects and decides how to model the relationship and the objects themselves in the graph.

The GraphGenerator is the upper level of the graph construction process. It is a wrapper around the GraphBuilder class that is intended to instruct the builder how to build the underyling graph structure.
